As energy saving equipment becomes more and more prevalent in facilities the need to discover where energy is being wasted is becoming more and more important. At the same time these pieces of energy saving equipment like motor drives and electronic lighting have the potential to disrupt the electrical system due to power quality problems. The Fluke 434 Series II Power Quality and Energy Analyzer can monetize the cost of energy waste due to poor power quality and is ideal for characterizing power quality, conducting load studies and capturing hard-to-find voltage events over a user-defined period of time. The Fluke 434 II Energy Analyzer is the ideal tool for advanced energy logging and energy monetization, identifying the most energy-wasteful areas of your facility.

With its energy logging capabilities and the Energy Loss Calculator function, the 434 II measures the fiscal cost of energy wasted due to poor power quality issues in real dollars. Add basic power quality measurements to the package and you’ve got yourself one powerful troubleshooting tool.

The Fluke 434 II Energy Analyzer is the best general purpose power quality and energy analyzer. If you’re looking for advanced power quality and energy analysis capabilities, the Fluke 435 II is second to none.

Applications

Energy Monetization – Calculate the fiscal cost of energy waste due to poor power quality.

Energy Assessment – Quantify the before and after installation improvements in energy consumption to justify energy saving devices.

Powerful Troubleshooting CapabilitiesThe Fluke 430-II products were specifically designed with the needs maintenance engineers and technicians in mind; users who need to get to the solution of the power quality problem as quickly as possible so that they can minimize expensive downtime. The measurement process and display of data is optimized to get to the most important information as quickly as possible. Multiple parameters are measured simultaneously and displayed in formats that quickly describe the state of the power quality of the system. Data can be quickly accessed as simple digital values, trend graphs, waveforms, phasor diagrams or analyzed and organized into tabular format such as the event data where the magnitude, duration and time stamping enable rapid correlation to problems experienced.

AutoTrend - Quickly See the TrendUnique AutoTrend gives you fast insight into changes over time. Every displayed reading is automatically and continuously recorded without having to set up threshold levels or having to manually start the process. You can quickly view trends in voltage, current, frequency, power, harmonics or flicker on all three phases plus neutral.

The System-Monitor Overview ScreenInstant insight into whether the voltage, harmonics, flicker, frequency and the number of dips and swells fall outside the set limits. A detailed list is given of all events falling outside the set limits.

Power Inverter Efficiency Power inverters take DC current and transform it into AC current, or vice versa. Solar generation systems usually include an inverter that takes the DC energy from the solar cells and converts it to useful AC power. Inverters can lose performance over time and need to be checked. By comparing the input power with the output power you can determine the system efficiency. The 430 series II can measure the efficiency of such inverters by simultaneously measuring the DC and AC power of a system to determine how much power is lost in the conversion process.

Unified Power MeasurementPreviously, only experts could calculate how much energy was wasted due to power quality issues; utilities could calculate the cost, but the required measurement process was beyond the reach of average electricians. With this patented Unified Power function you can use one handheld tool to determine how much power is being wasted, and calculate exactly what the extra consumption costs.

Fluke’s patented Unified Power Measurement System provides the most comprehensive view of power available, measuring:

Parameters of Classical Power (Steinmetz 1897) and IEEE 1459-2000

Detailed Loss Analysis

Unbalance Analysis

These UPM calculations are used to quantify the fiscal cost of energy loss caused by power quality issues. The calculations are computed, along with other facility-specific information by an Energy Loss Calculator that ultimately determines how much money a facility loses due to wasted energy

SystemMonitor - Check Performance Against EN50160 with EaseThe unique System-Monitor gives you an overview of power system performance (there is no button or single function) and checks the compliance of incoming power to EN50160 limits or to your own custom specifications. The overview is shown on a single screen, with color-coded bars clearly indicating which parameters fall outside the limits.

Track harmonics up to the 50th, and measure and record THD in accordance with IEC61000-4-7 requirements
